Seeing her chance to tell Matt about Abbie's behaviour when he's not around, Elly took it.
"I don't know how Matt's going to take this, but I'm hoping he sees that I just...I want what's best for him and I just want him to make the right decision," she explained in a piece to camera before stealing Matt away. "He needs to finally see Abbie for who she really is."
"What I really, like, need you to know is that I really like you and I'm here 110% for you and, like, you're a priority for me.
"I don't like talking ill about people but I just don't think Abbie is taking this thing very seriously... I don't know if she has the most pure intentions."
So, could it have finally started to dawn on Matt that Abbie might not be exactly who he thinks she is?
"It's interesting to hear that Elly thinks that Abbie's got the wrong motivations for being here because Elly's not the first to suggest that," he pondered in a piece to camera, still not entirely convinced.
"I do appreciate you telling me... I imagine it is, it can be uncomfortable because these people you're living with, I get that."
But things got even more uncomfortable when Elly and Abbie then had it out ahead of the rose ceremony.
Basically, Elly was pissed because she'd said she wanted first chat with Matt that night, but Abbie had swooped in the second he entered the room and grabbed him away, totally breaking the girl code in Elly's mind.
Emma's, too, for what it's worth.
"I'm not sure why Abbie felt the need to railroad Elly again in tonight's cocktail party but she doesn't really seem that bothered by it all," Emma mentioned in a piece to camera.
An astute observation, apparently.
"To be honest, I don't feel that bad about me grabbing Matt before Elly," shrugged Abbie. "Just because Elly wanted to have time with Matt first doesn't mean that I should be giving that time to her. I'm here literally only for Matt. I'm not here for Elly."
"Why would I send Matt over to speak to you when we are in direct competition to fall in love with this man because of this stupid, arbitrary line that we all made up in an effort to be diplomatic? It is absolutely ridiculous."
"Honestly right now I couldn't care less if the girls in the house love me or hate me - all I care about is Matt. And the only reason why Elly is so upset is because she feels threatened by me and because she hasn't gotten her way."
Do us a favour - grab the popcorn, will you?
